| 摘 要： | 以相思树样本的克拉森木素含量为研究对象,利用多波长下的近红外光谱数据建立了若干个预测木素含量的子数学模型.使用加权平均值公式给出了木素含量的首次近似值.根据木素含量实验值与近似值之间所具有的较强线性关系,给出了建立近红外光谱数据预测模型的迭代法.模型的预测精度随迭代次数的增加而提高.本迭代法有望用于其它树木某些化学成分...

| Abstract: | Using contents of Klason lignin of acacia specimens as an object of study,several sub mathematical models that can be used to predict the contents of lignin were built by using near infrared(NIR) spectral data of multi wavelength.Then,the first time approximation values of the contents of lignin were given by the weighted mean value equation.From the relatively strong linear relation between the experiment values and the predicted values of the contents of lignin,the iterative method of constructing predict... |
